Product details
Overview
SBR1A30T5 from Diodes Incorporated is a 1A Super Barrier Rectifier (SBR®) in SOD523 package, rated for 30V peak repetitive reverse voltage, with max forward voltage of 0.57V at 1A and max reverse leakage of 0.2mA at 30V/125°C. It serves as a high-efficiency, thermally stable rectifier or freewheel diode in compact DC/DC converters and AC/DC adapters.
For engineers reviewing the SBR1A30T5 datasheet, SBR1A30T5 pinout, SBR1A30T5 application, or SBR1A30T5 equivalent, key selection criteria include ultra-low VF at high current, <0.2mA IR at 125°C, 10A non-repetitive surge rating, SOD523 footprint compatibility, and patented avalanche ruggedness versus Schottky alternatives.
Technical Context
This SBR device uses Diodes' proprietary Super Barrier structure-distinct from standard Schottky or PN junctions-to achieve lower forward voltage than conventional PN diodes while maintaining superior avalanche energy handling and thermal stability of reverse leakage. Its 15ns reverse recovery time enables efficient operation in high-frequency switching topologies.
The SOD523 package delivers 160°C/W junction-to-ambient thermal resistance on a 1-inch² copper pad, supporting continuous 1A conduction up to +125°C ambient when derated per Figure 4. Junction capacitance is 95pF at 1V reverse bias, enabling predictable high-speed behavior in snubberless flyback or synchronous rectification circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 30 V - Maximum blocking voltage before breakdown; defines safe operating range in 24V rail rectification. |
| IO | 1 A - Continuous average forward current; supports compact 1A DC/DC output stages without heatsinking. |
| VF max | 0.57 V @ 1A, 25°C - Enables >92% conduction efficiency at 5V output, reducing power loss vs. standard Schottky. |
| IR max | 0.2 mA @ 30V, 125°C - Ensures stable blocking under thermal stress; prevents thermal runaway in sealed enclosures. |
| tRR | 15 ns - Supports switching frequencies up to ~5 MHz in flyback or buck converters without excessive ringing. |
| RθJA | 160 °C/W - Requires minimal PCB copper area for thermal management in space-constrained portable designs. |
| CT | 95 pF @ 1V, 1MHz - Predictable capacitive loading for EMI filter design and gate-drive coupling analysis. |
Pinout & Package
Package: SOD523 - ultra-compact surface-mount plastic package (0.80 × 0.60 × 0.30 mm), cathode indicated by band, matte tin-plated alloy 42 leadframe, RoHS-compliant and halogen-free.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to source side (e.g., switch node or transformer secondary); low-resistance path into barrier structure. |
| Cathode (banded end) | Forward current exit / reverse blocking terminal | Connected to load or output capacitor; withstands 30V reverse bias with sub-μA leakage at 125°C. |
Key Features
| Feature | Design Value |
|---|---|
| Patented SBR® technology | Enables Schottky-like VF with PN-diode-level avalanche ruggedness-no catastrophic failure under 10A surge events. |
| Ultra-low VF at 1A | 0.57V max reduces conduction loss by ~15% vs. typical 0.65–0.7V Schottky diodes, directly improving system efficiency. |
| Stable high-temp IR | 0.2mA max at 125°C ensures consistent blocking performance in automotive cabin or industrial ambient environments. |
| SOD523 footprint | 0.80 × 0.60 mm body enables placement in <1.0mm board thickness applications, including wearables and USB-C PD adapters. |
Applications
| DC/DC Converter Output Rectification | AC/DC Adapter Secondary Side |
|---|---|

Use Value: 0.57V VF cuts conduction loss by 80mW vs. 0.65V alternative, lowering die temperature by ~12°C at full load. |
Use Scenario: 12V/1A wall adapter for IoT gateway with limited airflow. IC Role / Device Role / Timing Role: Freewheel diode in discontinuous-mode flyback secondary winding. Use Value: Stable 0.2mA IR at 125°C prevents output voltage drift during sustained high-ambient operation. |
| Automotive Body Control Module | Industrial Sensor Node Power Supply |
Use Scenario: Reverse-polarity protection and load dump clamping in 24V BCM power input stage. IC Role / Device Role / Timing Role: Blocking diode upstream of LDO regulator, exposed to transient surges. Use Value: 10A IFSM and SBR ruggedness prevent failure during ISO 7637-2 pulse 5a events where Schottkys fail. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar super barrier rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SBRT1A30T5-7 | Same SBR® die, but optimized for tighter VF distribution (0.48–0.54V typ); 10% higher cost. | Better suited for battery-powered devices requiring precise efficiency budgeting. | Select when VF consistency across production lots is critical for thermal margin validation. |
| VB110L-GS08 | Standard Schottky; VF = 0.45V typ @ 1A but IR = 1.5mA @ 125°C - 7.5× higher leakage. | Acceptable only in low-temperature, well-ventilated applications. | Avoid in sealed or automotive environments where thermal runaway risk exists. |
Compared with SBRT1A30T5-7, the SBR1A30T5 offers broader VF tolerance at lower cost, while VB110L-GS08 trades higher leakage for slightly lower initial VF-making it unsuitable for high-temperature reliability-critical designs.

FAQ
Is SBR1A30T5 suitable for automotive applications?
Yes-SBR1A30T5 meets AEC-Q101 requirements for discrete semiconductors. Its 150°C maximum junction temperature, stable 0.2mA IR at 125°C, and 10A surge capability make it appropriate for under-hood and cabin modules. Automotive qualification documentation is available upon request via Diodes' PPAP process.
What is the recommended PCB pad layout for SOD523?
Diodes specifies a 0.70 × 0.60 mm solder pad with 0.15 mm solder mask opening and 0.10 mm stencil aperture for optimal reflow yield. Thermal relief traces should connect to ≥10 mm² internal copper planes. Full dimensions and land pattern files are published at diodes.com/package-outlines.html under SOD523.
How does SBR technology differ from standard Schottky diodes?
SBR uses a modified epitaxial structure with integrated guard rings and tailored barrier height-achieving VF close to Schottky (0.57V) while eliminating soft breakdown and enabling 10A IFSM. Unlike Schottky, it avoids catastrophic failure under avalanche stress and exhibits logarithmic IR increase with temperature instead of exponential.
Can SBR1A30T5 replace a 1N5817 in existing designs?
Yes-with caveats. SBR1A30T5 matches 1N5817's 1A/30V rating but offers 0.57V VF vs. 0.45V typ for 1N5817. However, its 0.2mA IR at 125°C is 20× lower than 1N5817's ~4mA, making it superior for thermal stability. Verify layout clearance: SOD523 (0.8×0.6mm) is smaller than DO-213AA (4.5×2.7mm).
